The Sensitivity of Anchorage Length to Splitting Failure in the New Eurocode 2

Abstract

In the new Eurocode 2 [1], the calculation of anchorage length has been notably modified compared to the previous version. The new formulation is significantly more sensitive to concrete splitting failure. In the previous version, the anchorage length could fluctuate by up to 30% due to effects such as splitting, reinforcement confinement, and lateral pressure. However, in the new Eurocode 2, due to the concrete splitting effect caused by the proximity of bars to each other or to edges, the anchorage length can increase by up to three times. Additionally, considering the effect of transverse reinforcement confinement can lead to considerable reductions in this length. Various graphical representations and examples are provided to quantify the sensitivity to splitting in the new formulation
